Display respective label if date is closer to due date in ScriptRunner

Jeremy Chee

I'm still learning how to create custom script fields on ScriptRunner (JIRA) and I'm working on this exercise where I am required to query for an issue's due date and display the respective label when it approaches the due date:
- "Green" - 10 days from the due date
- "YELLOW" - over 4 days but less than 10 days away from the due date
- "RED" - less than 4 days from the due date

Here's the solution to my question if anyone is curious 

---

```

import java.time.Duration;

import java.time.LocalDateTime;

import groovy.xml.MarkupBuilder

def dueDateField = issue.getDueDate();

def fieldContent = "";

if(!dueDateField) {

    log.warn("Due date doesn't exist on this item")

    fieldContent = "Due date doesn't exist on this item"

    return;

}

def currDate = LocalDateTime.now();

def daysRemaining = Duration.between(currDate, dueDateField.toLocalDateTime()).toDays();

def messageColour = "";

StringWriter writer = new StringWriter()

def builder = new MarkupBuilder(writer)

log.warn("due date field: $dueDateField, current date: $currDate");

log.warn("difference: $daysRemaining");

if(!dueDateField) {

    // log.warn("Due date doesn't exist on this item")

    fieldContent = "Due date doesn't exist on this item"

    return;

}

if(daysRemaining <= 4) {

    messageColour = "error"

    fieldContent = "You have less than 4 days left till this ticket is due!"

} else if (daysRemaining >= 10) {

    messageColour = "success"

    fieldContent = "There is still $daysRemaining days remaining until this ticket is due."

} else {

    messageColour = "warning"

    fieldContent = "There is only $daysRemaining days remaining until this ticket is due."

}

builder.div(class: "aui-message aui-message-$messageColour shadowed") {

    p(class: 'title') {

        strong("$fieldContent")

    }

}

writer.toString()

```
